Improved washing-machine



A kUNITED STATES PATENT Ormeaa SQUIRE AINSVVORTH, OF PITTSBURG, PENNSYLVANIA.

IMPROVED WASHING-MACHINE.

Specification forming part of Leiters Patent No. 98.902, dated January 18, 1870.

To all whom, it may concern,.-

Be it known that I, SQUIRE Ainswonrn, of

Pittsburg, in the Vcounty of Allegheny and State of Pennsylvania, have invented an Improved Washing-Machine, and I do hereby describe-the same.

, The object of my invention is the provision of a compact and simple washing-machine,

. tub and removable therewith.

The accompanying drawings, `made a part,

of this specification, represent a crank-machine constructed according to my invention. Figure 1 is a plan view; Fig. 2, a vertical section on the line z z, Fig. l.

Similarv letters of reference indicate like parts in the two gures.

A in lthe drawings may represent an upright tub, of suitable structure and material, and B a hinged cover, with which the same is pro- `vided.

A rotary rubber, consisting of a corrugated disk, C, provided with a perpendicular stem, D, is attached to theAtub-eover B, and projects,in the closed position of said cover, Within the tub, said attachment being of such charaeter as to permit of thevertical movement of the rubber, its stem passing through the cover. It may consist of a pin, d, traversing the rubber stem above the cover. The rotary or oscillating motion is imparted to the rubber C through a bevel-gear, E, through which its stem D passes, and it is held to its work by a spring, F, coiled around its stem and bearing against a shoulder thereon. Asquare or other non-circular opening in the gear E, embracing a corresponding portion of the stem D, connects them. A

The driving mechanism consists of a bevelgear, G, mounted on a horizontal shaft, H, and

actuated by a crank, I, or a'lever. The shaft- H is supported in brackets J, attached to the tub-cover B. An annular plate or ring, K, surrounding the central opening, provided in the tub-cover for the rubber stem D, forms a step for the gear E. A casting, L, of proper shape, forms an upper bearinggfor said gear and a cap to protect the same.

The spring F has its upper bearing on the' gear E. Its lower bearing may be at the disk of the rubber a, (shown in Fig. 1,) in which case it may be secured by its end f being introduced through or under the stem, as represented.

The tub is preferably made of wooden staves and bottom, corrugated ontheirl inner sides.

It is also proposed to make it of corrugated sheet metal.

Operation: In use, the tub being supplied with water and the clothes to be washed placed in it, while the cover and its adj'uncts are re- `moved, the cover is closed, bringing the rubber down on the clothes. Motion is then imparted to the rubber by the crank or lever,

while the rubber is held down with an elastic pressure by its spring. A

The clothes, being kept constantly soaked with the water andpressed and rubbed be,- tween the rubber and the corrugated sides and bottom of the tub, are rapidly cleansed.

I claim as myinvention The washing-machine herein described, con-` sisting of a corrugated tub, A B, rotary rubber G, rubber stem D, spring F, gears E G, step K, cap and bearing L, shaft H, bearings J, and a crank, I, or a lever constructed, comlloined, and arranged as set forth, for the purposes shown.
